In the aftermath of the Oklahoma tornadoes, patients weretreated in emergency clinics for a variety of conditions:


Sid-bleeding heavily, blood pressure dangerously low

Sally-hysterial hyerpcentilation, alkalosis, bording onasphyxia

Vic-disoreinted; blood volume and pressure low, but plasmaosmoality=320 mOsm


The solutions available for IV treatement at your clinicwere:

a. normal saline

b. d5W (5% dextrose in water)

c. d5-0.45% saline

d. 0.45% saline


1. Compared to normal body conditons (osmailirty=300 mOsm)solution c is:

A. hyperosmotic by hyptonic

b. hyperosmotic but isotonic

c. isosmotic by hypotonic

d. isosmotic and isotonic


2. write the ltter of the best solution, or write none if nonapply. Which solution is most appropate as threatment for:

sid_____ sally ______ vic________


3. which solutions could produce the following when applied toan indivudal with osmolarity= 300 mOsm.

ECF volume increasess ECf osmolairty decreases, icf volumesdecreases, icf osmolarity decreases

explain:


4. Sid as the following measrements: D2O volumes= 45 L inulinvolume=15.5 L plasma osmolairty= 300 mOsm.

Suppose he lost 0.75 L of blood, before the medics at anotherclinic administered an IV containing 1 L of d5-0.9% saline.

a. if 100% of dextrose moves into his cells, by how much doesICF solute increase?

b. what is his icf osmolairty after additon of the IVsolution?
